Y MEANS non OPERATING WINDOWS Appucauon sied August 29.1921 seria; No. 2416.038.

This invention relates to window operating arrangements and more particularly to arrangements whereby windows may be opened land closed, without touching the` same and from a distance.V 'A

, An object of the invention is to vprovide simple and eiicient meansv for opening andv framev of the windowand through which c Cords fastened at suitable points pass to per# mit opening and closing of the window by pulling on one end of each of the cords. In

order to prevent binding or sticking of theV window during movement thereof the pulleys before mentioned are provided 'withrollers adapted to rotateagainst the window frame. It is also desirable that the pulleys be fastened to the window frame in such a manner as to permit accurate adjustment of the same relative to the Casing of the window whereby the rollers carried by the pulleys may be positioned to bear against the casing .of the window for the purpose before explained.

Other features and objects of the invention will become apparent by lreference to the `following detailed description read in the light of the accompanying drawings wherein, v

Fig. 1 is a view showing the invention as installed upon the upper shafts of a window; Fig. 2 is a side view partly in section of one embodiment of the doublepulley utilized in the invention;

Fig. 8 is a section taken on the line 3-3 of Fig. 2;

5 Fig. 4 is a view similar to Fig. 2 of a modified arrangement of the doubley pulley, and

Fig. 5 is a vertical section illustrating the manner in which the pulleys are mounted upon the window itself.

Referring now to the drawings and particularly to Fig.'1, 10 indicates the frame of a window to which are secured a pair of doublepulleys 11. A small single, pulley 12 is` fastened to the top of the window casing in any desired manner. 'A' pair of cords 13 and 55 14 pass through vthe pulleys'as indicated and have one of their 'ends vfastened to any suitable portion of the Casing as indicated at 15 and 16 respectively.' As shown in Fi 1 the i cord 18 passes through the pulley12t rough 00 each ofthe double'pulleys 11 and isfastened to the top of the'window casing as indicated at 15. Likewise the cord 14 passe'sthrough the double pulleys 11'and is fastened to the p4 window casing as indicated at 16. Since the pulleys 11 are provided `with double pulley rollers the cords Varerpermitted to pass there-VVV through independently ofeach other.' v

Referring now to Figs. 2 and 3, the pulley 11lis composed of framework 17 having 70 mounted` therein twofpulley rollers 18 so arrangedas to rotate about substantially the same axis but so mounted as to-bevseparate A from eachother and also to be independently rotatable. l'lhefcasing 17 is providedwith 75 slots 19 at both the top andbottom thereof through which pass bolts 2()v for a purpose to be hereinafterexplained. -The casing 1"!A is also provided with a pair of extensions 21 between which a roller 22 is mounted' for 80 rotation in'any desired manner as'for example by means of. a stationary shaft v23 passing through and secured to each of theeXten-t sions 21; The bolts '20 are providedV at one end with a suitable thumb screw head 24 for 85 permitting manual tightening and loosening there-of.' As shown in Fig. 3 the threaded portion of the bolts 20 is .of larger diameter than that portion' of the rod passing'through 'the 'slot 19. For this reason and on account' 90 the type shown in Fig. 4 is'illustrated. ItV

is to be understood, however, that the same arrangement is utilized in connection with a pulley of the type illustrated in Figs. 2 and 3. The bolts may then be screwed into the threaded interior of the hollow screws 30 until the head 24 coming into contact with the casing 17 holds the pulley casing firmly against the window frame. Since the casing is provided with the slots 19 the position of the pulley may be adjusted by loosening the bolts 20', shifting the pulley and then turning the heads 24 until the pulley is firmly secured to the frame.

In order that that portion of the cords ,13 and 14 extending between the pulleys 11 may be substantially concealed from sight and also to prevent sagging of the same, telescop- `ing members 32 similar to vcurtain rods are mounted upon hollow extensions 31 or 31 of the pulley casings depending upon the structure of pulley used. The telescoping members 32 lmay be clos-ed hollow members or may in the case ofv curtain rods.

For assembly it is necessary onlyV to screw the hollow internally threaded Iscrews 80 into the frame of the window one above the other near the edge of the frame. The pulleys are thensecured-to the frame in the manner before explained, care being taken to insure that the external guide rollers rest against the window casing in such a manner as to'prevent lateral movement of the window. The cords 13 and 14 may then be inserted through the respective pulleys and one end of each fixed to the casing as illustrated inFig. 1.

Having assembled the device let it be assumed that the window is in the position illustrated in Fig. 1, that is, the sash is in its uppermost position. To open the window it is 'merely necessary to pull the free end of cord 14. Since the opposite endy of cord 14 is secured to the window casing, such pull will result in the lowering of the window. A pull exerted on cord 13 now causes the raising of the window. During vertical movement of the window the external guide rollers rotating-against the surface ofl the window casing prevent the window from bind-v ing or stickingas heretofore has been found to occur'when noy arrangement is utilized to have a portion thereof opened as is common prevent lateral movement of the window when a pull is exerted on either of the cords at the sides of the window. The telescoping members may be used to conceal the expanse of cords 18 and 14 lying between the pulleys and also to prevent the cords from sagging down across the face of the window.

I claim:

1. The combination with a window of a pair of multi-roller pulleys mounted in a casing securing to said window on opposite sides thereof, cords so arranged with respect to said pulleys that manipulation of the cords causes raising and lowering of said window, and means for preventing binding of said window against the window casing during movement thereof comprising guide `rollers mounted between projections extending from the casing of said pulleys in peripheral contact with the window casing.

2. The combination with a window of a pair of multi-roller pulleys secured to said window on opposite sides thereof, said pulleys mounted in a casing, cords so arranged with respect to said pulleys that manipulation of the cords causes raising and lowering of said window, and means for preventing binding of said window against the window casing during movement thereof comprising guide rollersmo'unted between projections extending from the casing of said pulleys in peripheral contact with the window casing, and means for concealing from view and for prevent-ing sagging of the expanse of cord between said pulleys comprising hollow telescopic members engaging and supported by hollow extensions from said pulley casings.

3. The window operating device comprising a pair of-multi-roller pulleys and a guide roller in combination, a window and cords, said pulleys and guide rollers secured t-o said window on opposite sides thereof, said pulleys adapted to cooperate with-the cords to raise and lower the window, and the guide rollers adapted, by making peripheral contact with the window casing, to prevent the binding of the window against the window casing duringY the movement thereof, substantially as set forth.

4. 'Ihe window operating device including the combination with a window of a pair of multi-roller pulleys combined with a guide roller and adapted to be secured to said window on-opposite sides thereof in such away' that when cords arranged with respect to said pulleys and-adapted on manipulation to raise or lower the window are operated, the 0'uide rollers will maleperipheralcontact with the window casing being thereby adapted to prevent binding ofthe window against the said window casing, substantially as described.

In testimony whereof, I have signed myV name to this specification.
